SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
IMPORTANT!
Safety instructions showed in this manual are useful to teach user
how to use the product in a correct and safety way with the
purpose of preventing possible personal injuries or property
damages.
Safety messages included here are classified as it follows:
WARNING
Be sure to take ESD (Electrostatic Discharge) protection measures when
you touch the board.
Otherwise, the optional board may get damaged due to static charges.
Implement wiring change on the optional board after checking that the
power supply is off.
Otherwise, there is a danger of connecting error and damage to the board.
Do not remove the cover except for periodic inspections or wiring, even if
the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
When connecting the gateway to the drive, wiring and periodic
inspections of both should be performed at least 10 minutes after
disconnecting the input power and after checking the DC Link voltage is
discharged with a meter (below 30VDC).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use cables with damaged insulation.
Otherwise, you may get an electric shock.
Do not subject the cables to the abrasions, excessive stress, heavy loads
or pinching.
Otherwise, you may get an electric shock.

CAUTION
Do not allow lint, paper, wood chips, dust, metallic chips or other foreign
matter into the board or drive.
Otherwise, fire or accident could occur.
WARNINGS
RECEPTION
Material of Power Electronics is carefully tested and perfectly packed
before leaving the factory.
In case of transport damage, please ensure that you notify the
transport agency and POWER ELECTRONICS: 902 40 20 70
(International [phone]) or your nearest agent, within 24hrs
from receipt of the goods.
UNPACKING
Make sure received merchandise corresponds with delivery note,
models and serial numbers.
Each board is supplied with a technical manual.
RECYCLING
The packing of the drives and devices must be recycled. For this
reason it is necessary to separate different materials (plastics, paper,
cardboard, wood …) and settle them in corresponding containers.
The residual parts of electrical devices must be collected in a selective
manner in order to warranty the correct environmental treatment.

SAFETY INSTRUCTIONS
SAFETY
Before operating the inverter, read this manual thoroughly to gain and
understanding of the unit. If any doubt exists then please contact
POWER ELECTRONICS, (902 40 20 70 / [phone]) or your
nearest agent.
Install the device according to the instructions within this manual.
Ensure that the mounting orientation is correct.
The Ethernet Gateway contains static sensitive printed circuits boards.
Use static safety procedures when handling these boards.
CONNECTION PRECAUTIONS
To ensure correct operation of the inverter it is recommended to use a
SCREENED CABLE for the control wiring.
Always check whether the DC Link LED is OFF before wiring
terminals. The charge capacitors may hold high-voltage even after the
input power is disconnected. Use caution to prevent the possibility of
personal injury.
COMMISSIONING
Follow the steps described in this manual.
Always apply voltage and current signals to each terminal that are
within levels indicated within this manual. Otherwise, damage to the
optional board may result.

1. INTRODUCTION
1.1. Ethernet Gateway
A gateway is a device that interconnects two networks of different
protocols and architectures. Typically, a gateway converts one protocol
stack into another.
Power Electronics Ethernet Gateway is used to interconnect Ethernet
(through MODBUS TCP/IP) with MODBUS RTU.
The Power Electronics Ethernet Gateway acts as a master in the
MODBUS RTU side and as a slave in the MODBUS TCP/IP side. This
manual gives the detailed description about the configuration and data
exchange in the gateway‟s MODBUS TCP/IP side.
The advantages of Ethernet networks are the following:
Easy installation and maintenance.
Flexibility for interconnecting different topologies.
Stable standard that allows interconnecting devices from different
manufacturers.

INTRODUCTION
1.2. Types of Ethernet Networks
There are different implementations for Ethernet network, according
to the physical environment referred. The existing Ethernet
technologies differ in the following concepts:
Transmission speed: Transmission capacity of the environment in
Mbps.
Cable type: Used technology of the physical layer.
Maximum length: Maximum allowed distance between two
adjacent nodes (without repeaters).
Typology: It defines the performance of the central linking points.

INTRODUCTION
The PE-GATEWAY supports 2 different modes of operation, which are
Pass-Through Only Mode and Cached Mode.
In pass through only mode, every MODBUS TCP request will be
processed transmitted over the serial line and the response from the
MODBUS RTU slave will be sent back to the MODBUS TCP master.
In cached mode of operation, initially the MODBUS TCP request is
passed through and queued in the cache of the gateway. The cached
requests are sent over the serial line, every configured period of time
and updated with the response.
Thus for subsequent requests from the MODBUS/TCP master, the
cached data is used.
When no pass through requests are pending, the cache is updated
once every time configured in the CACHE POLLING TIMEOUT
parameter. When the MODBUS/TCP master does not request any
data registered in the cache already, the corresponding entry is
invalidated within CACHE INVALIDATION TIMEOUT.
